RAIL ANCHOR.

Application filed October 7, 1926.

Our invention relates to an adjustabley rail anchor which is adapted to fit rails of different sizes and prevent the latter' from creeping longitudinally on grades and at other points along a railroad track.

One advantage of the invention is that it has but few working parts and no bolts or other parts likely to get out of order.

A furtheradvantage is that it does not require the drilling of holes in the rails or otherwise impairment of their strength in order to apply the rail anchor.

Another object is that if a track equipped with the devices should creep slightly it will only serve to clamp the ancho-r more firmly in place by turning it at a slight angle from a vertical plane.

Tith the above and other objects in view which will hereinafter appear, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a side elevation of the device being applied to the lower portion of a rail.

Fig. 2 is a side elevation of the device partly in section and in locked position upon the rail.

Fig. 3 is an end view of the device in locked position upon the rail and abutting one of the cross ties.

In carrying out the invention, a tension bar 2 is employed which is formed at one end into a rail engaging clip 4 having a spring loop 6 to cause .said clip 4 to firmly grip the adjacent flange A of the rail B. The loop 6 is so formed that it has sufficient clearance at one end to receive the fiange B when the device is forced into position preparatory to clamping it into place. The clip 4 converges towards the main body of the tension bar 2 so that it is forced on the upwardly sloping flange A it will firmly grip the latter.

The tension bar 2 is preferably made of spring steel and provided intermediate it@ terminals with a resilient loop 8. The tension bar 2 is bowed slightly and tapers towards one end, said tapered portion being provided at its under side with a plurality of serrations 12 for engagement with the tooth 14 of a removable clamp member 16,

Serial No. 140,018.

which is substantially U-shaped in form to straddle the serrated end of the bar 2. The upper portions of the clamp member 16 have jaws 20 which extend inwardly towards the web C of the rail. The undersurfaces of said jaws 20 are beveled as indicated at 22 to correspond with the bevel of the adjacent rail flange D and provide a wedging fit thereon.

In practice the devices may be placed in any suitable numbers along the track, but are preferably placed on grades and near stations where the rails are more apt to creep due to the starting and stopping of trains. In applying one of the devices, the clip 4 is first driven onto the rail flange A, which action slightly straightens out the bowed part of the tension bar 2 and compresses the spring loop 8. The clamp member 16 is then placed upon the serrated end of the tension bar 2 and driven forward until the jaws 20 firmly grip the upper surface of the rail flange D, which action further straightens the tension bar 2 and causes the upper portions of the loop 8, the clip 4, and the jaws 20 to more firmlygrip and hold the rail from creeping longitudinally. Before the clamp member 16 is driven home the device is moved against one side of a crosstie E which coacts with the device in holding the rail from creeping, Fig. 3. Other lof the devices may be Iso placed with relation to adjacent cross ties as to prevent the track from creeping in an opposit-e direction.

While we have shown a preferred embodiment of the invention, we reserve all rights to such changes and modifications as properly fall within the spirit and scope of the invention as claimed.

Having thus described our invention, what we claim and desire to secure by Letters Patent, is:

1. A rail anchor comprising a bar having a rail engaging clip at one end and a loop intermediate its ends, and a removable clamp member adapted to slidably engage the free end of said bar and also the upper surface of one rail iange.

2. A rail anchor comprising a slightly bowed spring bar having a rail engaging clip at one end and a loop intermediate its ends, and e removable clamp member adapted to adjustably engage the Yfree end of Said bnr and also the upper surface of one rail flange.

3. A rail anchor Comprising :1 bar having a ruil engaging Clip at one end land Serratons at its opposite end, and a removable elmp member adapted to sldably engage `the upper surface of one ruil flange und hnv- 10 ing a tooth for engagement with the serrutions on the bar.

In testimony whereof' we affix our signatures.
